Explain how one can rate the closeness of related organisms by comparing dna base sequences

1 answer:

6 0

Scientists believe we all originated from one common ancestor. using our dna base sequences, we can determine how closely related organisms by looking at when the first differing sequence occurs. for example, U U T A you can determine that
U U T T 1 and 2 are more
U U A T closely related than 1 and 3 because their dna sequence stays the same for longer. hope this helps :)
